Issues regarding the quench oil tower in ethylene plants
Thread Content
In the current design of quench oil towers, there is usually a flow of quench oil that is sent to the quenching components of the pyrolyzer in order to cool the pyrolysis gas. With the total amount of quench oil remaining constant (the amount used for quenching plus the amount that returns), how does the temperature at the bottom of the quench oil tower change? It would be useful to have relevant simulation data or empirical data available.
I can’t understand your area of research... The simulation data for quench oil towers is very complex, and the effects you mentioned are minor.
As mentioned above, the simulation data for quench oil towers is quite complex; I don’t think the issue you’re referring to will have a significant impact on the temperature at the bottom of the tower. The factors that affect the temperature at the bottom of the tower are mainly the operating load of the pyrolysis furnace, the composition of the pyrolysis products, the inlet temperature to the tower, the circulation volume of the quench oil and the mid-stage reflux flow, the DS pressure, the amount of pyrolysis tar recovered, and the amount of gasoline recycled.
